One is the type which existed in your case (Saving some lines of code), the other thing however is the actual implementation of that lambda function. I think it will create a temporary call-container object on each invocation (just like the instance of the anonymous class you would use in java). Wonder if that is a correct or incorrect asumption on the runtime behaviour of that syntactic construct. Bernd Thanks Mark, I was however refering to two things.

A lot of the setup of the service is the same due to us using WCF to do service interactions. I think you probably would have more code if you didn't have TServiceClient yeh. @Bernd – I think we had the carrying object (ServiceClient?) anyway even without passing in the service call as a function.

In your example you have TServiceClient, if you would not have a Type, it would take more code, right? I yesterday hat the same problem (in Java), the whole in the middle is quite common. Unfortunatelly we do not have the lambda construct there (see the code in my german blog post: http://itblog.eckenfels.net/archives/441-Lambdas-in-Java.html ) Greetings Bernd Do you know if this results in creation of an additional call object (carrying the args for the lambda expression)?
